RigbyM,
If you can find a copy of With rifle in 5 Continents by Paul Niedick it is a good read. Mr. Niedick uses a 10 bore paradox to dispatch an Indian elephant, a hippo and a buffalo. He often reaches for the Holland in sticky situations or for the coup de gras. He also has a couple of comments on the recoil of the gun and at times seems quick to hand it off to another in the hunting party. I think a big 10, as bore guns go, is the perfect balance between power and recoil.
